| Title | Failure to Complete Extent of Condition Reviews for the Stator Drop Significant Condition Adverse to Quality Event |
| Description | The team identified a Green finding and an associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, because the licensee failed to follow procedure EN-LI-102, Corrective Action Program, which required verification that the required action has been completed as intended. Specifically, for the extent of condition reviews for the stator drop event, two corrective actions were closed even though the actions were inadequate. The licensees corrective actions included re-performing the actions and documenting the failures in the corrective action program as condition reports CR-ANO-C-2016-00479 and CR-ANO-C-2016-00480. The failure to complete two of the extent of condition reviews associated with the stator drop event specified in the associated corrective action plan was a performance deficiency. The performance deficiency was determined to be more than minor because, it was associated with the design control attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the failure to complete actions related to identifying and correcting the extent of condition for a significant condition adverse to quality could potentially lead to an initiating event. The finding was evaluated using Inspection Manual Chapter 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, and Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 1 Initiating Events Screening Questions, dated June 19, 2012. The team determined the finding was of very low safety significance (Green) because the inadequate closure of corrective actions did not cause a reactor trip or the loss of mitigation equipment relied upon to transition the plant from the onset of a trip to a stable shutdown condition. This finding had a problem identification and resolution cross-cutting aspect of Resolution because the licensee did not take effective corrective actions to address issues in a timely manner commensurate with their safety significance. Specifically, the scope of the actions taken as part of the corrective actions did not resolve the issue as describe in the corrective action statement [P.3]. |
